MinGW and compiler optimization

Tril · Nov 26, 2005, 07:46 AM

I have a newbie question.

When using MinGW on windows to compile libraries to be used with windows, is there an option to turn on automatic SIMD optimization (SSE, SSE2) like on Microsoft Visual Studio .NET 2003?

MinGW uses a special version of gcc 3.4.2.

I'm looking for an easy way of optimizing ffmpeg if it's possible (by the simple activation of an option, etc). Maybe I can add optimization to be used by gcc by adding some gcc's switches in the configure file.

If someone knows something about it, please share your information and give lots of details. Newbies usually need a detailled step by step explanation to understand.

Thank you in advance.
